That's the problem. The archives should have several threads about
this shortcoming in either the relevant APIs or their implementation.
I.e., the request attributes will be there if you ask for them by
name, but they don't appear when using that (or simlar) API calls,
IIRC.

As an aside, you don't need PHP to check for attributes,
/Shibboleth.sso/Session and log files (e.g. the SP's transaction.log
for attributes, httpd's access.log for REMOTE_USER) should suffice.
